Analysis of the Differences in Identification and Delimitation of Intra-urban Green Areas in Rio de Janeiro by the Mesoscale Perspective of the MapBiomas

Abstract

Contributing to the environmental quality of the urban landscape, green areas have functions allied to the rescue of collective spaces in cities. Through Remote Sensing and Geographic Information Systems it is possible to map and monitor urban green at different scales. The MapBiomas initiative has the potential to monitor the annual evolution of land cover and use throughout the national territory, and adapting this base to scales at the municipal level is a challenge. In this sense, the present work seeks to analyze the urban green in the city of Rio de Janeiro, bringing an evaluation of the representativeness of these data and analyzes referring to the dimension and spatial distribution of the green areas in their context. Although the representation scale is not ideal, the use of this dataset is justified by the richness of 35 years of annual maps. The data also enable socio-environmental diagnoses, such as the elaboration of the Index and the Percentage of Green Areas, which in 2014 in the municipality reached values of 49.46 m²/inhabitant and 26.05%, respectively
